Dingoo A320 forum

Did you test it on your pc or on the dingoo?

The kexec-releases won't compile on mipsel without some obscure patching (no idea for wich version those patches are), that's why I ask.

I've done it on the dingoo, I was able to compile kexec statically without any patch.

And I had also built a kernel with kexec support.

It worked well, but I had to use a 'vmlinux' kernel file, not the normal zImage.

The difference is that the vmlinux is not compressed.

great to hear it works. I just wonder why the kernel has to be uncompressed, kexec should have support for zImages as far as I read.

So, for a mplayer-setup, we would need the normal zImage for uboot, 2 vmlinux-images and 2 entries for dmenu ("media mode" = kexec -l vmlinux-media "normal mode" = kexec -l vmlinux), right?

yes, right

The fact that only uncompressed image works can be fixed in user space I think, it should be doable.

But for now we could use this workaround.

Nevertheless, the kexec support might enlarge the kernel a (small) bit.

Hi,
i just uploaded a small comparison Video of the Native Player and Mplayer.

As you can see mplayer works better, for some reason the native player freezes from time to time.

PS: at the end of the video is a small mkv/H264 playing on dingux, a filetype that wont work on the native firmware at all

Hey can someone upload the video used to test it.

I just compiled mplayer from the latest official sources (so not the ones from igenics ftp). But i don't know much about mplayer. I had to disable a lot for it to compile and link but i managed to get it working. It plays an 320x240 mpeg fine using fbdev but the onscreen console interferes a bit with it so goana try with the sdl driver now to see how that goes.

hi joyrider.

You won't get acceptable performance from native mplayer. 320x240 mpeg might be fine, but xvid etc. are totally out of scope. You are way better of using the binaries I provided or compiling ingenics sources yourself (though that ain't really easy).
The onscreen console interference and problems with the osd are probably due to missing double-buffering in dingux.
